We present a generic surface deformation framework for the problem of 3D shaperecovery. A spatially smooth and topologically plausible surface mesh representation isconstructed via a surface evolution based technique, starting from an initial model. Theinitial mesh, representing the bounding surface, is refined or simplified where necessaryduring surface evolution using a set of local mesh transform operations so as to adapt it tothe local properties of the object surface. The final mesh obtained at convergence canadequately represent the complex surface details such as bifurcations, protrusions and largeconcavities. We demonstrate the performance of our deformation framework on theproblem of shape from silhouette and its fusion with shape from optical triangulation for3D reconstruction of static objects. The framework is in fact very general and applicable toany kind of data that can be used to infer 3D geometry. Since the approach we take forsurface deformation is Lagrangian, that can track changes in connectivity and geometry ofthe deformable mesh during surface evolution, the proposed framework can also be used tobuild efficient time-varying representations of dynamic scenes.Keywords: 3D reconstruction, shape from silhouette, shape from structured light, shapefrom optical triangulation, surface deformation, surface evolution.
